基于光敏電阻的照明燈控制系統(tǒng)的設(shè)計(jì)摘 要隨著信息技術(shù)的飛速發(fā)展和社會(huì)的不斷進(jìn)步，人們都市生活的迅速發(fā)展，新型半導(dǎo)體材料LED照明應(yīng)用得到普及，人們對(duì) LED 照明的高效控制和功能多樣化的要求也不斷提高。燈飾除了有普遍的照明作用之外，還有廣泛的工業(yè)用途。針對(duì)普通的LED光源存在光譜不全這個(gè)問題，本文介紹了一套小型智能燈，它是基于光敏電阻的照明系統(tǒng)，主要的功能是用光照強(qiáng)度來調(diào)節(jié)LED燈的亮度，就是通過光敏電阻接收到的外界不同的照度來控制LED燈不同的亮度，也就是說，本設(shè)計(jì)通過環(huán)境光照度的強(qiáng)弱對(duì)LED燈進(jìn)行控制，而且可以自動(dòng)變換，使生活和工業(yè)生產(chǎn)更加現(xiàn)代化和節(jié)能環(huán)保。這個(gè)設(shè)計(jì)的核心在于單片機(jī)控制模塊，光敏電阻通過外界照度的不同產(chǎn)生不同大小的電信號(hào)，本設(shè)計(jì)先根據(jù)電信號(hào)的大小規(guī)定好對(duì)應(yīng)的數(shù)字信號(hào)，這樣單片機(jī)就可以根據(jù)輸入的數(shù)值信號(hào)發(fā)出紅綠黃三路通路/截止的命令，達(dá)到辨色的目的，判斷光強(qiáng)度做好防護(hù)，并且可從液晶屏上讀出光照強(qiáng)度，調(diào)控LED光強(qiáng),這樣的設(shè)備在溫棚、禽舍、曬相、電路板生產(chǎn)等方面都得到廣泛的應(yīng)用。關(guān)鍵詞：LED(發(fā)光二極管) 光敏電阻 單片機(jī) 液晶顯示屏LIGHTING CONTROL SYSTEM DESIGN BASED ON PHOTORESISTORABSTRACTWith the rapid development of information technology and social progress as well as the rapid development of urban life, new applications of semiconductor materials are popular LED lighting products. Efficient LED lighting and functional diversification of the requirements is also rising. Lighting not only have lighting effect, but also have extensive function of industry. This paper introduces a set of small smart lights, the lighting system which is based on photosensitive resistance, to solve LED light source for general spectrum insufficiency problem. Its main function is to automatically select the light color. Photoresistor receives different illumination of the light outside to control the three RGY-LED work or not. In other words, a lamp can automatically transform several colors light. It will save the energy sources make our life more modern . The SCM (Single Chip Micyoco) module is the core of this design. Photoresistor generated different signals by different external illumination. The design first turn analog signals into digital signals.Accroding the digital signals, SCM will release the orders to control RGY-LED work or not.In this way, the purpose is able to choose colors of the light intellectuality.At the same time it can read the light intensity On the LCD panel to regulat the intensity of Lighting system . Such equipment Have extensive application on Greenhouse, birdhouse, bask in phase, circuit board production.朗讀Key words: LED(Light Emitting Diode) Photoresistor SCM LCD顯示對(duì)應(yīng)的拉丁字符的拼音目 錄摘要IABSTRACTII1前言11.1選題的目的意義11.2國(guó)內(nèi)外研究綜述11.3研究目標(biāo)11.4研究?jī)?nèi)容21.5關(guān)鍵問題21.6基本思路21.7研究方法22基于光敏電阻的照明燈控制系統(tǒng)的設(shè)計(jì)和論證32.1設(shè)計(jì)要求32.2設(shè)計(jì)方案32.3方案選取63基于光敏電阻的照明燈控制系統(tǒng)的設(shè)計(jì)73.1基于光敏電阻的照明燈控制系統(tǒng)的整體電路原理方框73.2電源設(shè)計(jì)73.3控制電路73.3.1STC12C5A60S283.3.2信號(hào)采集電路103.3.3LCD顯示電路113.3.4驅(qū)動(dòng)調(diào)光電路124單片機(jī)編程154.1程序流程框圖154.2信號(hào)采集程序154.2.1AD初始化程序154.2.2AD轉(zhuǎn)換程序164.3顯示屏程序164.3.1寫指令函數(shù)164.3.2寫數(shù)據(jù)函數(shù)164.3.3顯示函數(shù)174.3.4對(duì)1602液晶的模式進(jìn)行設(shè)置184.4主程序（選擇紅、綠、黃指示燈的程
